   Invited

   We introduce a new Quasi-Parametric Chirped-Pulse Amplification (QPCPA) scheme for intense laser, which can suppress the back conversion significantly through depleting the idler. On one hand, it can support high signal efficiency close to quantum-limit. On the other hand, it is robust against phase mismatch, so it has a broader wavelength bandwidth and a larger temperature tolerance. These characteristics make it a promising method for producing higher peak power lasers.Authors: Jingui Ma, Shanghai Jiao Tong University
